Brass bulkhead connectors

SKU: 284215376135191

Brass bulkhead connectors to help you fit your hosed heater coil to  your hot tub setup. Choose from the drop down menu according to the size of tube in your coil (25.4mm or 32mm). 


Buy a 32mm Starrett hole saw drill bit - ideal for drilling holes to accomodate our brass bulkhead connectors for both 25.4mm and 32mm hosed coils. NOT FOR USE WITH EXTRA LONG CONNECTORS.


We also provide extra long brass connectors for hot tubs with very thick walls (or wooden barrels!). 


If you have an electric hot tub that you are looking to convert to wood-fired, you may be able to use a pair of hose barbs on their own with your tub's existing connection sockets. Our hose barbs come in two sizes:

25.4mm barbs for 1"/25.4mm hose, with 3/4" BSPT

32mm barbs for 1-1/4"/32mm hose, with 1" BSPT.

Please contact us first if you are unsure whether the hose barbs are compatible with your tub's connection sockets. 






    Ensure that the coil is placed a safe distance from your hot tub and is both stable and secure. Please take particular care of how and where you use your heater coil in any settings where children or animals may be present - safety should be paramount at all times. Any attachments/ connectors/high temperature hose you choose to use should be well clear of the flames.

    It is advisable to conduct a brief common sense safety check of the setup before firing the coil. The coil should be set away from any thoroughfare and flammable materials etc.  

    Please note that your cold water inlet and hot water outlet feeds must be below the water level in your hot tub at all times when your coil is in use. If the water line in your tub is below the level of your warm water outlet feed from your coil (or drops below it while you are using your tub) water will stop flowing through your coil and just sit in it, becoming extremely hot. This is called 'dry firing' the coil, which is extremely dangerous and will result in scalding hot water or steam coming out of the hot water outlet. 

    ​If you have a stocktank style hot tub, we would advise attaching it to your coil with the hot water outlet below the upper ripples in the tank.
